MACHINEYFO'R WEAVING TUBULAR eoons To all whom it may concern:

Be it known that I, WILLIAM MURPHY, a

subject of the King 'of Great Britain and; Ireland, residing at 150 Broughton road, Pendleton, Manchester, in the county of Lancaster, England, engineer, have invented new and useful Improvements in Machines? "for Weaving Tubular Goods, of which the;

I the article-d,irepresented asa sack, being following is a specification.

My lnvention relates to machines which are used for weaving tubular fabrics such as sugar bags, bags for inclosing animal carcasses, endless printers blankets up to'about SIX feet in diameter, ventllatin'g pipes for ships, tubes for covering rollers, and for weaving tubular goods generally.

It consists essentiallyin the provision of means for beating or pressing the weft in such goods as they are being woven so as to effect a closely woven fabric. In machines to which my invention relates the warp...

threads are conducted within a ring or tube of a diameter corresponding with the diameter of the tubular goods or thereabout, and the weft is inserted by a shuttle or shuttles actuated in a path concentric with the axis of the tubular fabric, a spreader connected with the shuttle being used, to direct the weft in the open shed.

The essential novel feature of my invention consists of a presser acting in conjunction with the ring and in a path coincident with the travel of the fabric, adapted to beat, or push the weft into the open shed and enable the fabric to be more closely woven than has hitherto been possible. For this purpose I use a device which acts at right-angles to the usual spreader to press the weft within the fabric and efi'ect a close weaving. This presser device may take various forms. For instance it might be a loaded rotary presser or a reciprocating rotary presser or hammer. And in order that my invention may be fully understood I have attached hereto three sheets of drawings to which I will now refer.

Figure 1 represents in elevation and partly in section so much of the type of machine referred to as is necessary to illustrate the invention, with my invention applied thereto, the machine being shown as weaving a bag or sack. Fig. 2 is a part of Fig. 1 but showing an outside view of the presser. Fig. 3 is a sectional view showing a modification of the presser device used in Fig. 1.

Specification of Letters Patent.

Application filed June 6, 1911. Serial No. 631,576.

' Patented J an, 16, 1912.

Fig. 4g is a similar-view 'to 'Fig. 1 but showing a further modified form 'of'presser.

Referring in the first place-to'Figs. 1 and 2 the dotted'lines airepresent the open shed, the-circles 6 indicating the shuttles." One, two or more "of such shuttles are used in the machine. spreade'rs 0 insert the weftin the open shed,

woven: within the-ring f :in the usual manner. The metal'tubeg. is driven by bevel gearing h z to actuate the shuttle traversing mechanism j secured to the tube 9 and part of which only is shown in the drawings. Vithin the tube 9 is disposed a metal tube is of smallerdiamet-e'r 'projecting'out' of the tube 9, and to this tube is secured a presser m. The presser m is secured to and rotates with the tube .9 by means of a set screw 9 disposed in a groove m formed in the presser. It will be seen from the drawings that the presser m rotates with the tube 9 within the ring f the flange m of the presser bearing upon the fabric (Z as it is being woven. A load is applied to the presser m, to enable it to press the weft in the fabric as it is inserted in the open shed. This load 1 may be varied as required. and is carried upon the upper end of the tube 70. To provide forthe changing of the shed the presser m is formed on its contact edge m with two oppositely arranged gaps m or more than two gaps if more than two shuttles are used. The shed is changed by means of these gaps the moment of change occurring when the shed is in the gap, the contact edge m of the presser m then following and acting as a presser to press the weft into the fabric. It will be understood, of course, that various diameters of ring f are used according to the size of thebags or tubes being woven.

I may if desired provide the presser m with bowls or runners at instead of having gaps as is illustrated in Fig. 3. In this case the bowls or runners rest upon the fell of the fabric and are adapted to press the weft into the fabric as it is inserted in the open shed, the shed being changed in the intervals between the bowls.

As stated instead of a loadedpresser I may use a reciprocatory one to beat the weft up as it is inserted and an arrangement whereby this can be effected is illustrated in Fig. 4. Parts of the apparatus in this figure are similar to those shown in Fig. 1 and In connection with each shuttle,

bear the same letters of reference. The presser m however, instead of being loaded is reciprocated as it is rotated to act as a beater in the following manner. The

presser m carried by the tube is is slidable within and rotatable with the tube 9 and is provided with snugs s disposed in slots 8 in the tube 9. Secured to the upper end of the tube 9 is a disk t provided with a number of cam surfaces 2?, upon which rests a bowl 6 rotatable in bearings in a lever 10 which is pivoted at one end to a collar u attached to the upper end of the internal tube is. The lever u is connected to a link '0 pivoted at 'v to the cross head 1" of the machine. It will be seen from an inspection of Fig. 4 that as the tube 9 revolves the revolving cam disk t acting on the bowl 25 will reciprocate the tube is and with it thehannner or beater m. The beater m is formed with projections w one for each shuttle used and these projections beat up the weft and press it into the fell of the tubular fabric. The spaces between theses projections allow for the changing of the shed.

So long as the spirit of my invention is preserved by using a pressing or beating appliance in conjunction with the ring with in which the tubular fabric is woven, I do not confine myself to any particular pressing device or mode of operating the same.

I declare that what I claim is.

1. In combination in machines of the indicated kind the ring f, a presser device m having means to permit the changing of the shed formed therein and resting upon the fabric, a load n to force the presser device upon the fabric and means for rotating the presser device, substantially as described.

2. In combination in machines of the indicated kind the ring f, a presser device having means to permit the changing of the shed formed therein, means to reciprocate such presser device to beat up the weft in- In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
